IMPROVEMENT IN STEAM-COOKERS.

Specification forming-part of Letters Patent No. 1 73,448. datedFebruary 15, 1876; application filed I January 18, 1876.

To an whom it may concern:

Be it known that I, HENRY DAVIS, of Erie,

in the county of Erie and State of Pennsylvania, have invented-certainnew and useful Improvements in Condensed Steam-Cooker; and I do herebydeclare the followingto be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being bad to the accompanyingdrawings, which'form part of this specification.

My invention relates to certain improvements in steam-cooking apparatus.

Heretofore steam-pans and cooking-utensils have been constructed with awater-vessel permanently attached thereto, and of' a form to allow ofonly the bottom and sides of the vessel to be enveloped in steam. p k

The object of my invention is to produce a cooking apparatus in such amanner that ev- .ery portion of the vessel Within which the substance isbaked or cooked may be completely surrounded by a steam-space and tothat end myinvention consists in the several distinctive features whichwill more fully appear from the tol-lowing description and claims.

Figure l is a side elevation of my cooking apparatus, and Fig. 2 is avertical section of same.

The outer vessel A is provided with a bail, a, handle I), and a duct orspout, B,-the latter serving to convey the condense water from the coverto the lower portion of the vessel A through opening b'in the lowerportion of the same. The interior or cooking vessel 0 is, preferably, ofconical form, and has a tube, 0, secured to its inner surface, the upperend of said tube terminating a little below the upper edge of thevessel. The tube 0 connects with the interior of vessel A throughopening 0.- Gover D, provided with a handle, (I, is formed with asteam-space, E, steam being admitted to the same through the shortdepending tube 0, which registers and enters tube 0 of vessel 0 as thecover is placed in its proper position on said vessel. Water ofcondensation, as it forms in the steam-space ot' the cover, is

conveyed through spout F into the duct B of vessel A. The spout Fissituated directly opposite the tube 6; therefore, to secure the coverto the vessel B, the spout is first inserted in the opening f of saidvessel, and the tube 0 is then forced into the tube 0 of vessel 0,thereby forming a continuous steam pas sage and space completely aroundthe bottom, sides, and top of vessel Br Within the upper portion of thecover there is placed a layer of plaster-paris or other non-conductingsubstance, G, to prevent the undue heating of the top of the cover. Avent-hole, g, is formed in the top of the cover, so that air maycirculate above the non-conducting substance, and thereby preventitsbeing continuously saturated with moisture, and allow of 2 itsdeposition on the top of cover D.

Any article of food, when placed within a steam-cooking apparatusconstructed as herein described, will be subjected to an even andequalized temperature around its entire surface, and thereby be evenlyand thoroughly 7 cooked or baked.

Having clearly described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination of receptacle 0, having a tube, 0, and opening f,with the cover D,

provided with tube e and spout F, substantially as and for the purposeset forth.

2. The combination, with receptacle A having duct B and opening I),vessel or receptacle O provided' with tube 0 and opening f, of the coverD formed with a tube, 6, and spout F, substantially as and for thepurpose set forth. 3. The combination of the non-conductor G with coverD, the same provided with a steam-space, E, substantially as and for thepurpose specified.

In testimony whereof I have signed my 'name to this specification in thepresence of two subscribing witnesses. I

HENRY DAVIS.
